The one dramatic series we watch regularly; over 22 seasons with 2 different detectives.
The above DVD shown was the first season of John Barnaby, played by Neil Dudgeon.
The series is set in an imaginary British area with different murders (3 or so, sometimes gruesome) each show. Atmospheres have often had a supernatural or weird edge. Several red herring characters typically in a show. Thoroughly engaging scripts, acting, scenery, camerawork, and music (spooky theremin theme).
The John Barnaby series also features two cute dogs so far (top: Sykes–retired, deceased, and below: Paddy).
